ABSTRACT:
A process for rolling wire or rod material, such as hardenable steel, high speed steel and copper phosphorous alloys, includes feeding the material continuously from a supply roll through a heating zone and a rolling device for rolling the material in at least two stages, wherein the material at room temperature has a low deformation capacity unsuitable for rolling in the rolling device and therefore is heated in the heating zone to a temperature of improved deformation capacity suitable for rolling, the temperature of the material is continuously measured between the heating zone and the rolling device, a determination is made as to whether the material has been heated to a predetermined deformation temperature appropriate for rolling, diverting any portion of the material determined to have a temperature other than the appropriate rolling temperature away from the rolling device to prevent the diverted portion from entering the rolling device and being rolled, severing the diverted portion between the heating and rolling and directing the material determined to have been heated to the appropriate temperature the rolling device and rolling the material in at least two stages.
